CARBURETER.

SPECIFICATION forming part of Letters Patent No. 765,108, dated July 12, 1904.

Application filed June 14,1902. Serial No. 111,700. (No model.)

To all whom, it meaty concern.-

Be it known that I, HENRY SOEDER, acitizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvements in Gas-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and, use the same.

My invention relates to gas-machines or carbureters, and more especially to such machines designed for charging air with hydrocarbon-vapor to increase or confer the illuminating or heating power, or, in other words, render the same combustible.

The objects of my invention are, first, to provide a machine in which the carbureted air when supplied from the machine shall be free from oily particles or impurities and be as far as possible saturated with the inflammable ingredient and thoroughly mixed.

Another object of my invention is to keep the formation of the gas regulated according to the consumption of the same, thus equalizing the pressure at all times within certain predetermined limits, sustaining said pressure and supply according to the consumption, thus providing a steady flame.

Still another feature of my invention is to provide a compact device within which the air is carbureted and stored and sustained in a saturated condition under pressure and being in said container in direct influence with the saturating medium, thus at all times keeping the air in a saturated condition while under pressure.

My invention consists in peculiar features, assemblage of parts, and details of construction, which will be hereinafter fully set forth, and especially cited in the claims.

In the drawings, Figure I is a view in longitudinal vertical section of a machine which embodies my invention. Fig. II is an enlarged vertical sectional view of the carbureting mechanism. Fig. III is an enlarged frag- A represents a tank of any suitable contour, 5 which provides the container for the hydrocarbon and also the reservoir for the storage of the carbureted air and also comprises or embodies the carbureter. This tank A is divided into two compartments by a diaphragm B, the compartment C being adapted to contain the liquid hydrocarbon, and the compartment D adapted to contain the carbureted air and also preferably the carbureter E. Leading into the tank A is a pipe F,which 6O enters at the lower portion of the carbureter E and is given an up-turn, as at f. The carbureter E is an elongated chamber preferably a large tube, tightly packed with an absorbing and filtering substance. I prefer for this pur- 5 pose to employ silk G; but other substances may be employed. The carbureter E at its lower end connects, as at 6, with a hydrocarbon in the compartment G, and at its upper end it connects, as at 6, also with the compartment C 7 O for the purpose of conveying the overflow, if any, in the carbureter to said compartment. The upper end of the carbureter E is left open and communicates with the compartment D, which is the reservoir containing the carbureted air.

The pipe F communicates with an air-pump, preferably one known as the force-pump.

It is, however, preferable that this pump should be operated by a medium of constant pressure, and for this purpose I employ therefor as a matter of preference a pump run by waterpressure or hydrostatic pressure. Thus when the pressure in the compartment I) is raised to a certain point predetermined the pump 5 will stop to operate, and when the pressure is lowered in the compartment D the pump starts to operate. These pumps are of such Varied construction and so well known that I do not deem it necessary to illustrate or de- 9 scribe the same in detail.

D represents an outlet or supply pipe which is connected to the service-pipe, and it is thus that the gas is conveyed to the point of consumption. This outlet is at the upper end of the the compartment O.

Charging-aperture A is supplied to the compartment 0, and cleaning-apertures (J and I) may be provided at the lower end of the compartments C and D for the purpose of cleaning out said compartments.

The following is the operation of my device, setting forth its peculiarities and advantages: The main difliculty heretofore encountered in the use of carbureted air has been the improper mixture of the air with the hydrocarbon vapor. Either the mixture was not thorough or where the mixture was thorough the air carried with it particles of liquid hydrocarbon, which affected the consumption in several wayslirst, in the consumption a disagreeable odor was emitted; second,- the combustion was irregular at times, flashing up.

ward and at other times decreasing in volume of flame, also sooty deposits were formed in the burner, and hence the same was choked up. All of the above disadvantages prevented to a great extent if not entirely the use of the carbureted air in connection with mantle-burners on account of the desired regularity of the flame and the smallness of the apertures in the burner through which said gas had to pass. All of the above difliculties and objections have been obviated by my invention, which operates as follows: A pump of predetermined pressure is connected to the pipe F, and the compartment C is provided with hydrocarbon to a point above the surface of the inlet 0. This hydrocarbon, preferably gasolene, passes through the nipple saturates the packing G, and percolates upward through said packing, keeping the same charged with more or less of the liquid hydrocarbon. The pipe F leads into the lower end of the carbureter E and having an upturned end f, which by reference to Fig. II can be seen to be so constructed that its outlet is directed upward, causing the air to be projected in this direction and through the saturated packing G, thus acting also as or on the principle of an ejector, pumping the hydrocarbon orsucking the hydrocarbon through the inlet or nipple 0, thus always keeping the packing saturated regardless of its percolating qualities. The air passes upward through the carbureter, thoroughly mixes with the hydrocarbon, taking the same up to a saturating-point; but by passing through the packing above the surface of the hydrocarbon the liquid hydrocarbon is filtered and the carbureted air passes out through the upper end of the carbureter E. If from any cause liquid hydrocarbon should be carried to the upper portion of the carbureter E above the level of the liquid in the compartment C, the same will pass into the compartment 0 from the carbureter E through the nipple e, which is located a short distance below the upper end or outlet of the carbureter. No communication is had between the compartment D and the compartment C, and hence the carbureted air as it passes from the carbureter E enters the compartment D, where it is stored and always under pressure, and. the action of the air through the carbureter keeps the airwithin the compartmentD always in action, inasmuch as its outlet being at the upper end and the newly-charged air being the heaviest will always tend to descend, as indicated by the arrows in Fig. I. Thus it will be seen that the air is always kept in agitation and always kept in saturated condition and that the heavier gases will always pass to the bottom, leaving the lighter gas to pass through the outlet D, from whence it passes to the desired place for combustion. The mixed air and hydrocarbon vapor being, as before stated, of

the lightest saturated quality, but at the same time fully charged, is not so apt to condense; nor have I found that it will condense in the service-pipes or parts of the burner, and hence choking and sooty formation are prevented.

Charging-orifice A for the compartment 0 is provided with an air-tight or gas-tight cover, as are also the hand-holes O and D which are provided to each compartment for the purpose of cleaning any sediment or accumulations in said compartments.

In setting forth this invention I have described and illustrated the same in a simple and convenient construction, with details and assemblages which I consider best adapted to carry out the object of the invention; but in doing so I do not wish to be understood as limiting my invention to these assemblages or details of construction, as the same may be modified in various ways and still retain the gist of my invention.
